Marine weather data you can trust

Our network of marine weather sensors provides real time confidence and reduces forecast uncertainty by up to 50%.

Ready to maximize voyage earnings and safety? Explore Wayfinder ship routing.

Our Wayfinder app provides captains with routing guidance that accounts for weather, market variability, charter party, and sea keeping. The objective optimization evaluates over 100 million route options every 6 hours, to provide dynamically updated waypoints and speed profiles on your operating schedule.

We own and operate the largest open-ocean weather sensor network. By assimilating this data into our global weather model, we produce wave and swell forecasts that are 20%-50% more accurate than NOAA and ECMWF.

The most accurate marine weather forecast. Anywhere.

Marine weather forecasts have been unreliable because they lack accurate real-time data. Our privately-owned network of open ocean sensors fills this data gap and reduces uncertainty in marine weather forecasts by up to 50%. A few lines of code give you more accurate real-time conditions and the best forecasts across our world's oceans.

Wind, Wave, and Temperature Data

Spotter collects 3D displacement time series and water temperature data. The 2D wave spectrum, surface wind velocity, and Sea Surface Temperature (SST) are calculated and stored onboard, and user-selected data is transmitted through satellite to the Spotter Dashboard.

Compact & Portable

Spotter can be shipped anywhere around the world, carried by hand, and deployed without any special equipment.

Solar Powered

Self-contained, low maintenance, and always ready to go.
